United Kingdom, Oct. 11 -- Liam Gallagher has become a grandad for the first time.

The Oasis rocker's daughter Molly Moorish announced the arrival of her baby boy Rudy on Saturday (11.10.25) with an adorable snap of her footballer boyfriend Nat Phillips holding the little one.

Molly, 27, captioned her Instagram post: "A message to you, rudy."

Liam fathered Molly in 1998 after a fling with singer Lisa Moorish - shortly after he had married actress Patsy Kensit - but was not involved in her life until she was 20 after years of estrangement.

Molly's mother Lisa expressed her pride on the social media site, writing: "That last slide!!! 'IM RUDY I'M NEW' My beautiful grandson."
